The WAC4P20 is a compact 4 Pole 20 A modular contactor offering silent, reliable switching for lighting, HVAC, EV and automation applications. It’s DIN-rail mountable and suitable for both single and three-phase control circuits where noise-free operation is essential.

Designed to fit modular enclosures and consumer units, it provides quiet coil performance and a long mechanical life. Compliant with BS EN 61095 and BS EN 60947-4-1, the WAC4P20 ensures safe switching for resistive and inductive loads under the 18th Edition Wiring Regulations (BS 7671).

Installer Tip: Use the 4-pole 20 A model for multi-circuit lighting or control systems that require neutral disconnection or multiple pole isolation. Keep coil and load cables neatly segregated to reduce induced noise on sensitive circuits.

  • Silent coil design – ideal for residential and commercial projects
